1 Claim. (01. 16719) My invention relates to compositions of matter fer to use phenyl mercury acetate and phenyl having germicidal, bactericidal and fungicidal properties and refers particularly to compositions of matter of the character mentioned containing mercury compounds and diethylene-gly- 5 monoethylether. col-monoethylether. I give the following as examples of the produc- I have found that compositions of matter contion of compositions of matter of my invention. taining certain mercury compounds, such as Example 1 phenyl mercury hydroxide or phenyl mercury acetate, and diethylene-glycol-monoethylether h e grams phenyl-mercury acetate. 50 cc. possess valuable germicidal, bactericidal and diethylene-gly l-m n hy t r, 037 cc. lactic fungicidal properties coupled it other propacid and 48.5 cc. water are added together and erties, which are suitable for many applications allowed to stand for several hours and 0.8 cc. where such properties are desirab1e ammonla added thereto.

properties.

From the mercury compounds suitable for the poses, they must be alkaline when employed with production of the matters of my invention, I precasein in which case their alkalinity may be as amount. usually about 0.1 per cent of an organic 3 great as 9.0 to 10.0; while when employed with organic water-repellent they must be acid.

These various degrees of alkalinity and acidity can be readily attained by adding ammonia or lactic, or other organic acid to the given examples.

My compositions of matter have many valuable applications where properties such as they possess are desired, among which are treatments of leather, rubber, glues and cosmetics.

I do not limit myself to the chemicals, amounts, pH degrees, alkalinities or acidities particularly mentioned, as these are given solely for the purpose of clearly describing my invention.
